Evolution

they first were big heavy uncomfortable metal contraptions that would normalls stand on legs or sit on your shoulder. they required reels on tape to record and you had to turn a crank to capture images which was hard to do unless you were a trained professional. they were in black and white. now video cameras are in color, some have handles and lcd screens. most are digital and take tapes. Now you can find cameras that shoot in 1080HD.
